[PATCH 0/2] vhost-scsi: Check for tcm_vhost ABI version
From: Nicholas Bellinger <nab at linux-iscsi.org>
Hi Anthony,
Here are the two patches against Zhi's vhost-scsi tree to check for
a supported version (VHOST_SCSI_ABI_VERSION=1) that's now exposed via
the tcm_vhost ioctl.
Please have a look and let me know if this is what you had in mind.
Thanks!
